Vinyl chloride resin composition for powder molding, vinyl chloride resin molded product, and laminate

Abstract

Provided is a vinyl chloride resin composition for powder molding that can provide a molded product having superior flexibility at low temperatures. The vinyl chloride resin composition for powder molding includes (a) vinyl chloride resin particles, (b) a plasticizer, and (c) vinyl chloride resin fine particles having an average degree of polymerization of at least 1,000 and no greater than 5,000.

The invention claimed is: 
     
       1. A vinyl chloride resin composition for powder molding comprising:
 (a) vinyl chloride resin particles having an average particle diameter of at least 50 μm and no greater than 500 μm; 
 (b) a plasticizer; 
 (c) vinyl chloride resin fine particles having an average degree of polymerization of at least 1,000 and no greater than 5,000 and an average particle diameter of at least 0.1 μm and no greater than 10 μm; and 
 (d) vinyl chloride resin fine particles having an average degree of polymerization of less than 1,000 and an average particle diameter of at least 0.1 μm and no greater than 10 μm, wherein 
 an amount of (b) the plasticizer per 100 parts by mass in total of (a) the vinyl chloride resin particles, (c) the vinyl chloride resin fine particles, and (d) the vinyl chloride resin fine particles is at least 70 parts by mass and no greater than 200 parts by mass. 
 
     
     
       2. The vinyl chloride resin composition for powder molding of  claim 1 , wherein
 (b) the plasticizer is at least one plasticizer selected from the group consisting of trimellitate plasticizers and pyromellitate plasticizers. 
 
     
     
       3. The vinyl chloride resin composition for powder molding of  claim 1 , wherein
 a vinyl chloride resin forming (a) the vinyl chloride resin particles has an average degree of polymerization of at least 1,000 and no greater than 5,000. 
 
     
     
       4. The vinyl chloride resin composition for powder molding of  claim 1 , wherein
 an amount of (c) the vinyl chloride resin fine particles relative to a total amount of (a) the vinyl chloride resin particles, (c) the vinyl chloride resin fine particles, and (d) the vinyl chloride resin fine particles is at least 3 mass % and no greater than 20 mass %, and 
 an amount of (d) the vinyl chloride resin fine particles relative to the total amount of (a) the vinyl chloride resin particles, (c) the vinyl chloride resin fine particles, and (d) the vinyl chloride resin fine particles is at least 2 mass % and no greater than 15 mass %. 
 
     
     
       5. The vinyl chloride resin composition for powder molding of  claim 1  used in powder slush molding. 
     
     
       6. A vinyl chloride resin molded product obtainable through powder molding of the vinyl chloride resin composition for powder molding of  claim 1 . 
     
     
       7. The vinyl chloride resin molded product of  claim 6  used as a surface skin of an automobile instrument panel. 
     
     
       8. A laminate comprising:
 a foamed polyurethane molded product; and 
 the vinyl chloride resin molded product of  claim 6 .
